の不良率が高いという問題があった。By the way, the shape of the movable valve body of the conventional single lever type hot / water mixing faucet is such that the hot water supply valve opening and the water supply valve opening are opened at one edge of a disk having a constant thickness. Since the open part for forming was made in a notch shape, the surface pressure of the whetstone was not evenly applied to the sliding contact surface during polishing, and a large surface pressure was applied to the open part, so the open part was excessive. The edge (shoulder) of the contact surface leading to the open portion is rounded and the so-called sagging occurs, and a gap is formed between the fixed valve plate and the adhesiveness is impaired. In addition, there is a possibility that foreign matter is likely to bite into the gap and the sliding operation may not be performed smoothly, and there is a problem that the defective rate of the product is high.

ず、水栓本体が大型化するという問題があった。If an opening is formed at the edge of the movable valve plate, hot water and water discharged from the hot water supply valve opening and the water supply valve opening can flow out only in the direction of the opening, so that the discharge port is moved in that direction. If not formed, the flow path resistance increases, so the location of the discharge path is limited, or a large discharge path must be formed around the mixing chamber so that the flow path resistance does not increase, and the faucet body becomes larger. There was a problem of doing.

がある。In this type of conventional mixing faucet, a bottom cover is engaged and fixed to the bottom of a cylindrical case constituting a mixing valve unit, and the fixed valve plate is housed on the bottom cover. Since the hot water supply valve opening and the water supply valve opening of the valve plate were assembled with a pair of communication holes formed in the bottom cover, respectively, the communication was performed through the gap between the faucet main body, the bottom cover, and the fixed valve plate. An annular packing is required to prevent water leakage from the hole, the number of required parts is increased, and assembling is also troublesome. Further, the annular packing deteriorates with time, or the dimensional accuracy of the rotating member, the fixed valve plate, etc. There is a problem that there is a risk of water leakage due to variations in the water content.

という問題があった。In addition, since the length of the cylindrical case is increased by the thickness of the bottom cover, the entire faucet becomes large, and the thickness of the fixed valve plate and the movable valve body must be reduced in order to reduce the size. There has been a problem that the flow path becomes narrow and the amount of discharged water is limited.

In order to form such a concave portion, it is necessary to form a sufficiently thick partition wall, and such a thick wall is liable to cause casting defects such as sink marks and nests during casting. Therefore, there is a problem that post-processing with high accuracy is also required, and the number of required man-hours is large.

It is an object of the present invention to provide a hot water mixing faucet. For this purpose, in the present invention, a movable valve plate that slides by operating a lever is closely arranged on a fixed valve plate of a mixing chamber, and a hot water supply valve opening and a water supply valve opening provided in the fixed valve plate are movable. In a single-lever hot-water mixing faucet that is opened and closed by sliding a valve plate, at least a part of a side peripheral surface at an intermediate portion in a thickness direction of the movable valve plate forms a cavity that communicates with the mixing chamber. In addition, an opening is formed in the sliding contact surface of the movable valve plate at a position away from the outer peripheral edge thereof so as to communicate with the cavity.

Although it is configured so as to be in close contact with the upper surface of the bottom wall 8 by the pressure reduction, the watertightness of this portion can also be maintained by such a configuration. Further, the fitting structure between the cylindrical case 15 and the fixed valve plate 16 can be engaged by providing the locking claws 22 with elasticity in the above-described embodiment. A cut may be provided to give elasticity to the lower edge of the locking hole 18.

製品を製作し得るようになるなど有益な効果がある。As described above, in the single-lever hot-water mixing faucet of the present invention, a cavity is formed as a movable valve plate at an intermediate portion in the thickness direction, and an open portion is formed apart from the outer peripheral edge of its sliding contact surface. Therefore, the sliding contact surface can be easily and uniformly polished, and a high-precision one having excellent water stopping performance can be manufactured. There are beneficial effects such as the ability to manufacture a compact product with little resistance and without sticking to the discharge path.
